Hi,

I've uploaded my first English document on the CFD for rotating machinery using OpenFOAM.
I'll revise this slide in the future to improve it and make it more useful to the new users of OpenFOAM.

http://www.slideshare.net/fumiyanoza...using-openfoam

Please let me know if you have any suggestions for which topics to cover

Hope this helps,
Fumiya

Hi,

I've updated ch. 3 to give a thorough explanation of MRF (Multiple Reference Frame) model in OpenFOAM.

I hope this helps.

Hi fumiya,
Thank for the slides. It really helps.
I would like to ask a question about SRFSimplefoam and MRFSimplefoam.
If a have a case that I run with MRF (stationnary and rotating frame) to get pressure drop inlet - outlet. And the same case I consider the whole domain (stators and rotor) as a single frame that is rotating and run it with SRFsimplefoam.
Should I have the same result? I will really appreciate if you can give me some clarification about that.
Thanks

Kossivi

Hi, Fumiya,

Thanks! Very helpful.

For a transient case using pimpleDyMFoam solver, what is your suggestion for delta t? I ran a case with 4000 rpm impeller speed. Delta t dropped to a very small value. Not sure if I did not setup the case correctly or the delta t needs to be very small. Any suggestion?
